Real-time controls such as the four knobs and the fader can be used to control instrument or mix parameters, even while you play. Professional-style pitch bend and modulation wheels allow you to add further articulation. The 3-digit LED display provides navigational feedback so it's quick and easy to find the right menus for changing MIDI channels, sending out program changes, transposing or programming the real time controls. And if 25 keys are not enough, press the octave up and down buttons to shift the keyboard range up or down instantly.

Installation is straightforward, too. Simply plug Masterkey 25 into a USB port on your computer and the operating system will do the rest. Masterkey 25 is USB class-compliant, which means that no driver is needed for supported operating systems.

Get a gripThe pitch bend / modulation wheels and the fader cap have a rubberized coating that provides additional grip, minimizing the chance of performers losing their grip. They look great and feel great on the fingertips too.

Real-time functionsBy default two buttons below the LED display operate as octave shift buttons -/+ extending the range of the keyboard 4 octaves up and 3 octaves down. The buttons can in addition be assigned to control Transpose, Program Change or MIDI Channel providing a total of 4 options. Press the two buttons at the same time, then scroll through the options using the - or + button until you have found the one you want.

ConnnectivityMasterkey 25 is easy to connect. One USB cable handles data transfer to your computer and also provides the power. It's also USB class compliant, so driver installation is not needed. All you have to do is switch the power button to On! An input jack is also available for an optional sustain pedal. Masterkey 25 automatically detects the polarity of the footswitch you connect, so any standard pedal can be used. If you don't have a pedal, check out the FP-1 and FP-2 pedals at the bottom of this page.

Assigning Controllers and EditMasterkey 25 would not be a controller keyboard without its real-time controls and the ability to assign MIDI CC's to each of them. Thanks to the LED display it's easy too. Once in Edit mode, pressing the black keys will show the various menu options. No need to refer to the manual or a keyboard chart, it's all there in the display. Select the key for assigning MIDI CC's and type in the number. It's that easy.
